Letters Patent No. 101,068, dated March 22,1870.

IMPROVEMENT IN` TINNERS AND SHEET-IRON WORKERS ROLLS.

The Schedule referred to in these Letters Patent and makingpart of the same.

To all whom it may eoucern Be it known thatvwe, AARON W. WHITNEY, PAR noN A. WHITNEY, and FOSTER A. WHITNEY, of Woodstock, in the count-y of Windsor and State of Vermont, have invented a new and useful Improve-l ment in Tinners and Sheet-Iron Workers Rolls; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings forming part of this specification.

This invention relates toy a new and useful improvement in the construction of rollers for tinners machines for working tin and sheet-iron or other sheet metal, whereby such rolls are rendered more durable than they have hitherto been, while the cost of manufacturing them is greatly reduced; and

It consists in making the roll and shaft or spindle of a single piece of east-steel, cast for the purpose, as hereinafter more fully described.

In the accompanying drawings- Figure l represents a sectional longitudinal view of the rolls 'and shaft.

Figure 2 is a section looking from the line :t x of fig. 1.'

Similar letters of reference indicate corresponding parts. v These figures are designed to showthe general shape or form of these rolls, for which no novelty is claimed, although by oury method We are enabled to make the -rolls lighter than they have hitherto been made.

A represents the roll, and

B, the shaft or spindle.

The rolls vary in the outline of their peripheries` or faces to adapt them to the particular purposes for which they are intended.

These rolls have hitherto been made by welding the steel roll A onto an iron shaft o spindle, B. This process involves a great amount of labor, requires much more material, and produces a roll greatly inferior to those for which we solicit protection by Letters Patent.

\Ve make our rolls and shaft of a single piece of east-steel, cast to near the required size, from a patlcern, thereby enabling 11s/to make the roll solid on the shaft, and also light in weight, by dispensing with a large quantity of metal, as 7seen by the `broad opening C.

As heretofore made, this space is solid metal, which is quite unnecessary, but indispensable in the welding process.

When the cast-steel casting is simply turned `to or finished up it is tempered and polished and is ready for use. By our improvement we produce au article greatly superior to the ordinary roll, andat a greatlyreduced cost.

Having thus described our invention, We claim as new and desire to secure by Letters Patent- As a new and improved article of manufacture, rolls for machines vfor working tin and sheet-iron, made of a single piece of cast-steel, cast for the purpose from a pattern1 substantially as described.
